The Osoto plot thickens.
This episode was largely more focused on Osoto, and setting up the challenge for what will be, presumably, the final plot. In it, we learn quite a few details.
Though they come out in a more dramatic order, I’ll cover the main reveals directly. One is that Osoto is responsible for at least Atori and Neko ending up at the hotel. Neko was a random attack, and she in fact did survive her stabbing, or so she is convinced. Atori seems more… purposeful. Based on a journal Osoto left that he allowed Neko to find, he seemed to have a massive chip on his shoulder about “that person” (Atori) and found killing to be an unsatisfying resolution, something that he is eager to right should he get the chance.
On Atori’s side, he doesn’t know Osoto. Rather, he knew Osoto’s parents, who were regulars at a hotel where Atori worked. It’s not clear how this gave Osoto his warped fixation, but it did, and now it seems he’s working on machinations to destroy and/or become Atori, per his wishes. As for Neko, he sees her as an interesting rival, literally citing her as the Holmes to his Moriarty.
Recalling that Moriarty seldom committed crimes himself and rather arranged them for others, it seems apt for how Osoto must operate under the rules of the Hotel.
Speaking of those rules, Neko makes it clear she isn’t happy with them. She confronts the manager, demanding if anything can be done about Osoto. The manager makes very clear that it is not his or the hotel’s role to interfere with transmigration to life, the afterlife, or Hell… but by his language does let slip that even if it must not be done, there is at least something that can be.
As to what that is, the monkey dude addresses Neko after her argument with the manager. He overheard (or spied on, however you prefer to take it) the conversation, and seems ready to offer Neko a way to deal with Osoto.
As for what that way is, what Osoto is plotting, and what Neko will do even if she does come into possession of a mechanism to deal with her Moriarty, that will have to wait until next week.
